CDM2

cdm2 is a designation that appears in multiple technical contexts and does not refer to a single, universal standard. In practice, "CDM" is often expanded as "Common Data Model" or, in some communities, as "Climate Data Management," with the suffix "2" indicating a second version or iteration. Because of this, the exact meaning of cdm2 varies by domain and repository.

In data interoperability and metadata schemas, cdm2 is commonly used to denote version 2 of a common data model intended to harmonize data elements across datasets. Such models aim to facilitate data sharing, integration, and cross-system querying by providing a standard set of data types, relationships, and qualifiers.

In geoscience and climate informatics, cdm2 can refer to a software toolkit or library that implements a data management framework compatible with established conventions and metadata standards. It may provide features for cataloging, metadata capture, and input/output of scientific datasets, though the specifics depend on the project.

In software development, projects named "cdm2" may exist as open-source libraries or components focused on dataset handling, serialization, and I/O operations. The languages, licenses, and capabilities of these projects are determined by the individual repository or organization behind them.
